Article 38CrMoAl surfacing 
 Basic low-hydrogen type, 38 for welding Cr-Mo steel and aluminum design, nitrogen treatment after welding to improve the hardness of 60 or more. Welding process, good crack resistance, can be AC and DC; workpiece preheat (200 ℃). Surfacing for low-carbon quenched and tempered steel and other parts wear surface. Hardfacing metal with AL ≤ 1.0%, Cr ≤ 2.0%, Mo ≤ 1.0%, ≤ 5.0% of other such alloys.
